I have the same problem,.. so far i replace the IAC and the idle still jumps up and down,.. next in line im going replace FITV ...im hopeing that does the trick,..the parts are not new but i have clean them well

 

I kind of agree with 93accordkid, although I hate throwing parts at the car.

I would pick up an air boost valve (#9) from the junkyard and swap that out. Explain your situation, and see if the junkyard will let you return the part if it does not solve your problem. I suggest the air boost valve first, because I have read more people having problems with that one. If that doesn't work, then try the IAC (called EACV on the 93 accord).

You probably already did this, but I would check that all the vacuum hoses are routed properly and not deteriorating causing the air leak. There should be a routing diagram under the hood so you can check all the vacuum hoses.

 

Luckily I can get the warranty on the part from my local PAP, so if that doesn't solve the problem, then I'll return it and get an IAC/EACV

Yup checked everything over by removing them one at a time and inspecting them. I even sprayed TB/Carb Cleaner around the connections and nada.

 

I bought a brand new IAC ($$$$ ) no change. Just for the hell of it I removed the ABV and plugged the hole. Voila' the idle dropped right to where it needed to be. :: SIGH ::

So what I did was I went to my local PAP found the same year model I have and pulled what I looked like a ABV delete plate. Bolted it in place of the ABV and have been enjoying being able to order in a drive through and actually being able to hear.

YAY!!!!!
